Error details and cause
An unsupported request was executed.
(The request was issued to CPU module which does not
support the request.)
An unsupported request was executed.
Command for which a global request cannot be performed was
executed.
A request was issued to the system file.
The volume of data to be handled by the specified request is
too large.
The CPU module is BUSY.
(The buffer is not empty.)
Because the CPU module is in the RUN state, the request
cannot be executed.
Because the CPU module is not in the STOP state, the request
cannot be executed.
The specified drive (memory) does not exist, or has an error.
The file with the specified file name or file number does not
exist.
The file name and file number of the specified file do not match.
The specified file cannot be handled.
The specified file is currently processing a request from
another engineering tool.
Specifying the file password set to the target drive (memory) is
required.
The specified range exceeded the file size.
The same file already exists.
The specified file capacity cannot be reserved.
The specified file has an error.
The request cannot be executed in the specified drive
(memory).
The request cannot be executed currently.
The specified device name cannot be handled.
• The specified device number is out of range.
• The CPU module does not support the specified device
name.
Corrective action
• Check the command data of SLMP/MC protocol.
• Check the CPU module name selected with an engineering
tool.
• Check the target CPU module name.
• Check the command data of SLMP/MC protocol.
• Check the CPU module name selected with an engineering
tool.
• Execute the request again.
If the same error code is displayed again, the possible cause is
a hardware failure of the CPU module. Please consult your
local Mitsubishi representative.
Check the command data of SLMP/MC protocol.
Check the command data of SLMP/MC protocol.
Check the command data of SLMP/MC protocol.
Execute the request again after arbitrary period of time has
elapsed.
Execute the request after placing the CPU module into the
STOP state.
Execute the request after placing the CPU module into the
STOP state.
• Check the status of the specified drive (memory).
• Back up the data in the CPU module, and then initialize the
memory.
Check the specified file name and file number.
Delete the file, and then create a file again.
Do not access the specified file.
Forcibly execute the request. Or, execute it again once the
processing from another engineering tool has been completed.
Specify the file password set to the target drive (memory), and
access it.
Check the specified range, and access within the range.
Forcibly execute the request. Or, change the file name and
execute the request again.
Review the specified file capacity, and execute the request
again.
Back up the data in the CPU module, and then initialize the
memory.
Execute the request again after placing the CPU module into
the STOP state.
Execute it again after a while.
Check the specified device name.
• Check the specified device number.
• Check the device assignment of the CPU module.
• Check the specified device name.
